# Reference Application
source: https://developer.mastercard.com/india-online-dispute-resolution/documentation/developer-tools/reff_application/index.md

The reference application shows a typical usage of the India Online Dispute Resolution API and how to integrate different operations in the Sandbox environment. You can either re-use or take code references for your implementation.

The reference application demonstrates how to call each India Online Dispute Resolution operation and integrate the required OAuth signing and JWE encryption. Each operation is provided as an independent, self-contained example that you can run and inspect on its own.

### What you will learn: {#what-you-will-learn}

> * How to use the reference application.
> * How to call each IODR operation independently, including OAuth signing and JWE encryption.
> * How to configure your application for the Sandbox and Production environments.
> * How to test your reference application.

## How the reference application is structured {#how-the-reference-application-is-structured}

Each operation is implemented as an independent, self-contained example. The positive and negative test cases run in isolation and generate their own data per call --- state is not shared between operations, so the output of one call is not automatically passed as the input to the next.

To understand how the operations relate to one another across a complete dispute lifecycle, see the [Use Cases](https://developer.mastercard.com/india-online-dispute-resolution/documentation/use-cases/index.md) page, which documents the end-to-end flow and process diagram.
